Power Banks

Choosing the Right Capacity

Key Features to Look For

Typical Uses

Smaller power banks (10,000–20,000mAh) suit daily commuting, office backup, and short trips where you just need a phone top-up. Mid-range units (25,000–43,800mAh) with USB-C PD output handle laptop charging for remote workers, train journeys, and weekend camping. The largest models (50,000–80,000mAh) are designed for extended off-grid use — multi-day camping trips, festivals, caravanning, and situations where mains power is unavailable for days at a time.

Common Questions

Can a power bank charge a laptop?

Yes, but it needs USB-C PD output with enough wattage. Most laptops need at least 45W–65W. The 140W PD models in this range can fast-charge MacBooks and Dell laptops at full speed.

How many times will a 50,000mAh power bank charge my phone?

A typical smartphone has a 4,000–5,000mAh battery. Accounting for conversion losses, a 50,000mAh power bank provides roughly 10–12 full charges.

What does PD (Power Delivery) mean?

PD is a USB-C fast-charging standard that delivers higher wattage than standard USB. It allows power banks to charge laptops, tablets, and phones much faster than a basic 5V USB port.

Are high-capacity power banks allowed on flights?

Most airlines allow power banks up to 100Wh (roughly 27,000mAh at 3.7V) in carry-on luggage. Larger units between 100–160Wh may need airline approval. Power banks must always go in hand luggage, never checked bags.
